IMPROVEMENT IN TROTTING-SULKIES.

specification forming part of Letters Patent No. 188,013, dated March 6,1877 application filed July 10, 1876.

To all whom it may concern:

' Be it known that I, DANIEL G. HETFIELD, of the city of Rahway, in thecounty of Union and State of New Jersey, have invented an Improvement in'irottingSulkies, of which the following is a specification:

The object of my invention is to render the axle-tree of atrotting-sulky more stifi' and stable, without materially adding to itsWeight, by means of the additional iron or steel braces a a, whichbraces are attached to the axle-tree much nearer its center than theusual braces b b, which make the attachment between the shafts or thillsand the axle tree. It also consists in the method of connecting the saidadditional braces on a with the usual braces 12 b at their commonjunction at the points 0 c on the shafts or thills. The plan view,Figure 1, shows the method of connecting them at their common junctionon the shafts or thills. The usual braces b b are attached to the shaftsor thills in the usual way, except that each one only occupies one halt'of the width of the shaft. In the inner edges of the braces b b a recessis made, as shown in the drawing, and a projection on each of theadditional braces on a fits into them, by means of which the two bracesare firmly fastened together at their junction 0 c on the shafts; and asany tendency to spring the axle by any obstruction in the track of thewheel will act in diverse directions on the braces a, a and b b, itfollows that the axle will be stiffened to the extent of theirdivergence from the point 0 0, both being connected to the shafts at acommon point, 0 c, and at dift'erents points to the axle, as shown inthe plan drawing, Fig. 2.

What I claim as my invention is- 1. In a trotting-sulky, thesupplemental braces a 00, attached to the thills and to the axle nearits middle, substantially as shown and described.

2. The brace 12, having its inner edge recessed, and the brace at,having a projecting lug adapted to fit such recess, in combination withthe thill of a trottingsulky, substantially as shown, and for thepurpose set forth.
